Top 31 best island beaches for swimming and snorkeling

0 Ratings

Plaza Sur is among the best snorkeling destinations in the world. Plaza Sur - South Plaza - is one of the smallest yet richest islands in the archipelago, known for its rich marine life. The abundant and friendly sea lions, the largest animals on the islands (with adult males weighing up to 550 pounds) are one of the main reasons snorkelers go there. Covering the seabed you'll also find damselfish, triggerfish, hogfish, sea stars, and urchins.


Stingray City, Grand Cayman

Stingray City is one of the largest tourist attractions in the world and one of the best animal encounters you can have. It is in 12 feet of water and is mainly, but not exclusively, visited by scuba divers. This series of shallow sandbars is home to tons of southern stingrays that divers and snorkelers can touch and feed with the help of a guide.


Buck Island, St. Croix, U.S. Virgin Islands

This 176-acre island just off of St. Croix has pristine white sand beaches perfect for swimming, but it's also the focal point of Buck Island Reef National Monument, which includes nearly 19,000 acres of submerged lands and coral reefs. Snorkelers can follow a marked underwater trail that helps identify features of the coral reef, which hosts rare and vulnerable fish along with three species of sea turtle. If you're looking for warmth and romance, the U.S. Virgin Islands are a fantastic destination, and St. Croix in particular is gorgeous.


Uepi, Soloman Islands

Uepi is a true snorkeling paradise. Whichever edge of the island you descend from, you'll find a fascinating underwater ecosystem. Uepi drops off into 165 feet of water at the Welcome Jetty and 6,560 feet at the Point. Two other popular snorkeling access places are the Lagoon and the Dive Jetty. You can look forward to marveling at coral "gardens," huge schools of fish, large gorgonian fans, vase sponges, lionfish and snowflake eels, plus many small invertebrates in the cracks and holes.



This beautiful tropical island nation is best known for its exceptional beaches, snorkeling, and topnotch diving. The water is so clear that many hotels have built overwater bungalows to accommodate guests. You can jump off your private balcony into the water and swim with exotic fish. Enjoy Technicolor coral, soft sponges, mantas, whale sharks, and pelagic fish that are regularly seen on almost any dive. If you are a certified wreck diver, you can explore the British Loyalty, a 450-foot tanker covered in coral reef.


Corn Islands, Nicaragua

These islands off Nicaragua have very diverse beaches. On the south end of Big Corn you can explore the most swimmable shore, which is a wide, sandy, baylike seaside. Take the road north from Casa Canada to come across a path with a very narrow beach, which has some great snorkeling, some in little protected coves. There are all sorts of coral and fish to swim with.


Champagne Reef, Dominica

There are several active volcanoes in Dominica, which affect the reef. Underwater geothermal springs vent gasses in the form of thousands of warm bubbles, giving snorkelers a feeling of swimming through a giant glass of Champagne. You can expect to see a myriad of sea life including sponges, lobster, parrot fish, and a resident population of Hawksbill turtles.


Molokini Crater, Maui, Hawaii

Molokini Crater alone is a reason why you should visit Hawaii in the winter. It offers a diving and snorkeling experience like no other. More than 200 species of fish reside there. Winter is the time to go, because this is when the water is the clearest - more than any other place on any of the islands - and not as choppy. You will probably hear the spooky sound of the whales "singing" if you go very early in the morning.



If you want to escape the crowds and still have a blast, consider Bonaire. Most of the 6,672-acre park is water. There is a no-anchoring policy for boats, but the nearly 60 species of coral underneath the surface are some of the most unspoiled in the world. The variety and scenery are unmatched in the region. Popular snorkeling sites include Karpata, Front Porch, and Captain Don's Reef.


Bay Islands, Honduras

The Bay Islands are made up of the islands of Utila, Roatan, and Guanaja. Home to a massive barrier reef, one of the most diverse in the region, the Bay Islands are a world class scuba diving and snorkeling site. Utila is the smallest of the Honduras Bay Islands, but it offers some of the largest underwater animal encounters in the Caribbean. The affordable pricing and easy access from the U.S. make these islands a popular snorkel destination.



Situated in the Indian Ocean southeast of Africa, Mauritius boasts bright blue waters, warm white sands, and tropical temperatures all year long. It is almost entirely encircled by a coral reef, which makes the island nation a superb destination for snorkeling. Mauritius has some of the most copious marine life in the Indian Ocean. A favorite place, especially for beginners, is the Lagoon, which is generally calm in the majority of places. Colorado and Roche Zozo are among the other most popular sites.


Ilha Grande, Brazil

This is a charming destination with astonishing waterfalls, lakes, secret coves, and secluded beaches. All of those make it an exceptional place for snorkeling and diving. The rich local marine life - as well as the several old shipwrecks - can be explored all year round, but November through May is the best time to snorkel.


Virgin Gorda, British Virgin Islands

One of the most popular of the British Virgin Islands is the Virgin Gorda, a land mass whose shape resembles that of a large reclining woman, and a place where the laid-back pace will wash all your worries away.

Other popular places are Savana Bay and Prickly Pear Island.

The wrecks and patchy reef system surrounding the islands host a tremendously diverse array of sea life.

Trunk Bay, St. John, US Virgin Islands

The U.S. Virgin Islands are one of many tropical destinations that don't require a passport for Americans. If you want to explore the Caribbean Sea, head to the absolutely serene Trunk Bay - but go early in the morning, because it gets really busy later in the day.

Big Island, Hawaii

No matter where you choose to start swimming on Hawaii's Big Island, you will never get bored, because you will be busy for a long, long time, marveling at what you see.

Baie Ternay Marine Park has the best underwater fauna from all Seychelles. Beauvallon, a small cove with small rocks on both sides, extends under the water with corals. You'll find here a lavish and colorful marine life. The right side of the bay consists of lush rocky islets. Swim there with butterfly fish, surgeon fish, and parrot fish.


Phi Phi Islands, Thailand

The coral reef systems of the stunning Phi Phi Islands are so abundant and astonishing you're going to need at least a month to explore them properly.

Hin Klang is in the middle of the sea, and Phi Phi Leh has a few more popular snorkeling locations such as Phi Phi Don and Bamboo Island.


Culebra, Puerto Rico
